SIMON INGERSOLL, OF NEWV YORK, N. Y.

SHINGLE-MACHINE.

Specification of Letters Patent No. 9,663, dated April 12, 1853.

To au 'whom t may concern Be it known that I, SIMON INGERsoLL, of New York, in the county and State of New York, have invented a new and Improved Machine for Cutting Shingles; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawings, making apart of this specification, in which- Figure 1 is a plan or top view of the machine. Fig. 2 is a longitudinal vertical section of ditto taken at the line X, X, Fig. l. Fig. 3, is a detached plan or a horizontal section of the reciprocating frame taken at the line Y, Y, Fig. 2, showing the lower bottom or surface of the frame on which the shingles are beveled.l Fig. 4, is a side elevation of a portion of the machine showing the manner in which the clasp that throws the shingles upon the bottom board is op erated.

Similar letters of reference indicate corresponding parts in each of the several figures.

This invention relates to an improved machine for cutting shingles from the block, and giving them the requisite bevel at one operation and with one and the same machine by means of a frame having a reciprocating rectilinear motion, said frame having a knife on its upper board or surface which splits or cuts a strip from the under surface of the block. Said strip after being cut from the block is thrown, by means of a clasp acted upon by a spring, upon the lower board or surface of the frame when it passes under a stationary knife or cutter which gives the aforesaid strip the desired bevel and thus form the shingle.

The employment or use of the spring clipper K, in combination with the riving knife, constitutes the invention.

To enable others skilled in the art to make and use my invention, I will proceed to describe its construction and operation.

A, represents a stationary frame having its top rails or side pieces (a) (a) inclined. See Fig. 2. On the upper surface of the side pieces are guide pieces (b) (ZJ), Figs. l and 2, on which a frame B, having a reciprocating rectilinear motion, travels. This motion is given the frame B, by means of a crank C, and connecting rod D. The frame B, iscomposed of two parts, one upper or top board (c) and an under or bottom board (CZ). These boards are connected a suitable distance apart by screws (e), Figs. 2 and 3, or their equivalents, so as to leave a space between them. The guide pieces (b) (b) above mentioned fit in grooves in the sides of the upper or top board (c).

On the upper or top board (c) there is a knife E, placed transversely on the board and at the elevated edge. See Figs. l and 2. Directly in front of this knife there is a bed F, on which the block G, from which the shingles are cut rests. See dotted lines. This bed is attached to the frame B, and moves with it. The edge of the knife E, is elevated a little above the top surface of the upper board H, is a stop placed transversely on the frame, as seen in Fig. l. The end of the block rests on bearers against this stop.

I, is a stationary knife attached to the top rails or side pieces (a) (a) of the frame A, and directly over the under or bottom board (d). See Figs. 2 and 3. The knife I, is placed transversely over the board (al) and in front of it there is a roller J, the ends of which lit in the inner ends of the levers (f) (f) having their fulcra at (g) (g). Springs (h) (it), one of which is seen in Fig. 2, bear against the outer ends of the levers (f) (f) and thus press the roller J, against the'bottom board (el).

K, is a clamp directly over t-he bottom board (d), of T shape. The end or shank of this clamp is attached to a rod placed transversely on the upper board (C). See Figs. l and 2. This rod (il) has at one end a lever (j), the outer end of which by means of a spiral spring (nl) bears on a projection (7c) attached permanently to one of the side rails (a) of the frame A. See Figs. l and 4C. 'This projection has an inclined plane (l) at its outer end and a spring (m) attached to the side rail (a) directly over this inclined plane, the uses of which will presently be shown.

Operation The block G, from which the shingles are cut is placed upon the bed F, the outer end of the block bearing against the stop H. Motion is communicated to the frame B, by the revolving of the crank C and the knife E, during the forward motion of the frame B, cuts od a strip from the under side of the block G. This strip passes of course under the knife E, and when the knife reaches t-he end of the block the clamp K, falls and throws the strip upon the bottom board This will be clearly understood by referring to Fig. 4. It will be seen that the spring throws down the lever (j) and consequently the clamp K, when the lever (j) passes beyond the spring (m) at the end of the projection (is) on the side rail (a), and upon the return motion of the frame B, the lever (j) and consequently clamp K, is raised by .passing up the inclined plane (Z) and forcing up the end of the spring (m). The lever (j) takes the direct-ion indicated by the arrows. Upon the return motion of the frame B, the strip cut olf by the knife E, at the forward motion of the frame passes underneath the roller J, and knife I, and as the position of the frame is inclined the strip is turned or shaved in beveled form in passing under the knife I, and a perfect form of shingle is cut.

It will be borne in mind that the knife I, is stationary and attached to the frame A,

and that the strip is thrown down by the clamp in front of the knife at the end of the forward stroke of the crank C.

Having thus described the nature and operation of my invention, what I claim as new, and desire to secure by Letters-Patent, 1s-

The spring clipper, K, operated as described, in combination with the riving knife, for the. purpose of insuring the complete separation of the shingle from the block, and at the same time throwing it on the lower bed, in position to be carried to the dressing knives, by the neXt advance of the driver, in the manner substantially set forth.
